Application filed April 27, 1911. Serial No. 623,701.

lie 11 known that l, itLiiXinoni: him/aim, a -itizen oi? the United States, :resid log at Gale and lii rnia, have invented certain new and is-it'ul l niprorenienls in tiaws, of which the "o lowing is a specification.

this invention relates to sewing machines and the principal object of the same is to provide a sawing machine that can be used tor cutting oil piles belou the Water line and in which novel means are provided for suspending the machine from the pile so that the saw thereof can be freely reciprocated.

A preferred and. practical embodiment of the invention shown in the accompanying driuviiigs, wherein Figure .l is a View in front elevation showing the sawing machine attached to a pile. Fig. 2 is a central vertical sectional view taken on the line 2-2 Fig. 1. Fig. 3 is a top plan View. Fig. t is an enlarged sectional View taken on the line 4r--4-., Fig. Fig. 5 is an enlarged sectional. View taken on the line 55 Fig. 1.

The iuuproved sawing machine comprises the upper beanie 6 and 7, beam 6 being the :lront and having angular end extensions 8. Qleani 7 is at the rear and has end extensions 9. The end extensions 8 and 9 are connected by the adjusting bolts 10, set screws 11 being carried by end extensions 9 to lock the bolts in their adjusted positions. Beams 6 and T are provided with eye bolts 12 to which the suspending arms 13 are swi'veled, said arms having angular free ends 14 that are sharp ened to permit them to be driven in the pile that is to be sawed. Beam 6 is provided with a central transverse seat 15 in which a dog 16 is pivot-ally mounted, said clog having one end sharpened for engaging the pile, and the other end 18 shaped to PI'OVlClB a handle :tor releasing the dog from said pile.

' lhe adjusting bolts 10 have sleeves 19 pivotally mounted thereon and saw 0perating rods 20 extend through said sleeves and are locked therein by the set screws 21. Said screws 21 engage Wear strips 22 carried y n the county of ililaineda and l'ltalc o t said rods. The lower ends of rods 20 are provideifl with reduced extensions 523 that are provided with central longitudinal slots Supporting arms 25 extend through slots 134i; and carry rollers 26 that engage opposite surlaocs oi? the extensions 23. The inner ends 27 of arms 25 are enlarged. and bifurcatml lor the reception of the ends of a saw blade 28, bolts 29 and nuts 30 being employed for fastening the ends of said blade in said bifurcations. The upper ends of rods 20 carry Weigl'its 31 Which faoilitale the necessary rocking movements oi? said rods.

The saw blade 28 is sl'idaliile in composed oi the guiding arms 32 which said blade extends and. the bracket 33 that connects said arms. is prorhled with a guiding loop 34: through which a vertical supporting rod 35 extends, the lower end of said rod being fastened to the bracket 33. is carried by a frame through angular Bea m (5 it. set screw 0 loop 34 tor adjustably locking rod 313 to beam An inclined guiding loop 337 carried by beams 6 and an inclined supporting rod 2-38 extends theretl'iri'iugh and has its lower end fastened to bracket 33. Rod 38 is adjustably locked. to the beam (5 by the set screw 39 that is carried by loop 37.

Rods 20 below beams 6 and 7 have stirrups t0 adjustable thereon for the reception of the feet ot the operators to assist in rock-- ing said rods.

The supporting rod 35 is provided with a shouldered portion 3? from Which an abut inent ll projects and contacts with the Work that is to be sawed to space the saw frame from said Work.

l i hen used in connection with piles forming parts of marine structures, the beams 6 and 7 are attached to the pile by the arms 13 and dog 16 above the Water line, W-l7i as indicated in Figs. 1 and 2 and the rods 20, 35 and 38 are adjusted to place the saw 28 and saw trains at the desired distance below said "water line. The beams 6 and 7 and the saw frame are stationary, and the saw is rer et l a r s the le by r k the rods 20. Two operators may be employed said guide, a saw blade passing through said 10 guide, and operating handles for said blade 1 carried by said bar.

In testimony whereof I ailiX my signature in presence of two witnesses. y I

to facilitate the sawing operation, one operator being at each rod 20.

What I claim as my invention is 1 A pile cutting device comprising a supporting bar, a rod adjustably connec'ted with i said bar, a saw guide carried by said rod, a diagonal rod connected with said guide and i supporting bar for regulating the angle of i Copies 0! this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
